Synopsis – MON DEC 15 2025

Mild conditions continue, then by Tuesday / Wednesday our ridge advances slightly Eastward, allowing a trough to push into the Northern portions of our forecast area. Low-order PoPs (20% – 40%) looks likely along the Sierra Crest, particularly from Mono County North. Light accumulations expected above 9K feet. The storm door remains open thru the weekend. Elsewhere, dry conditions persist in the Owens Valley until about Friday in the Owens Valley…DMATT
